I love a dog with an underbite. There's something inherently sweet about it. My rescue Dutch Shepherd, Ginger Peach, shows her lower teeth when she’s relaxed. Her goofy grin reminds me of our late Catahoula, Desoto. He had an underbite that could charm anybody. He’d go up to a complete stranger, reveal those baby bottom teeth and offer his paw, like he wanted to shake on an agreement that he’d be cute and you would feed him, okay? Whatever you had at hand—that turkey sandwich or hot dog—would be just fine. And people would give their food to him because apparently, they love underbites, too. Does your dog have an underbite? If so, please post a photo of your dog's best toothy smile on Bark's Facebook page.
